Abstract (en)
A method and apparatus for establishing a point-to-point-to-point telephone connection (L1,L2) between a remote telephone (10) and a desired called telephone (12). The method and apparatus use a two-line base telephone unit (14), e.g., a home or office telephone, as an intermediary point in the telephone call to reduce long distance rates and/or to utilize features and/or information stored in the base telephone unit when the user is away from the home or office. In a first embodiment, the remote telephone makes a local call to the base telephone unit and instructs the base telephone unit to establish a telephone call with, and interconnect the remote telephone to, a called third party. In a second embodiment, the remote telephone makes a quick call to the base telephone unit instructing the base telephone unit to establish and interconnect both a telephone call back to the remote telephone and a second telephone call to the desired called telephone. In a third embodiment, the instructions from the remote telephone to the base telephone unit are transmitted through an external communication link such as a paging system or the Internet. <IMAGE>
